I changed the default_build_method in
lino_welfare.modlib.welfare.settings from ‘appyodt’ to
‘appypdf’ because above list of examples is not very useful if the
documents are odt files. They were odt files because in the beginning
I was not running Running a LibreOffice server on my development machine as a
service, which caused the test suite and invbd to fail when I
had forgotten to manually start oood before launching them.
